would have been 一定为虚拟语气?
The London Olympics are about to begin,and spectators will again be riveted by feats that would have been impossible when the modern Olympics began in 1896.
为什么该句用了would have been impossible?“本应impossible的,但事实上不是impossible”?然而,从内容方面讲,在1896年本就impossible,事实的确impossible,并无虚拟啊.

would have been 还可以表示过去将来完成时
如：he told us that he would have finished his paper by that time.
再问：过去将来完成时一般都说过去某个未完成的任务将会完成例如 XX would have finished it by 3 p.m.。该句话怎么理解呢？1896年认为以后将变得impossible？1896已经impossible了，用过去将来时就可以了，完成时怎么理解呢？
再答：我仔细听了一下听力，没有听到have这个单词，文稿应该是would be impossible，be与 im连读之后会听成been，但绝没有出现have。所以正确的应该是：The London Olympics are about to begin, and spectators will again be riveted by feats that would be impossible when the modern Olympics began in 1896.
